Keep your warranty
I will keep your warranty or get a lexus extended, if you take that 1800 and save it it will not cover squat if your car breaks, you just bought and 70k car all parts are expensive, I just used my warranty to cover minor issues and the repair costs was 15k i got my seat motors replaced and my side mirror will not fold in got that replaced cause it was broken, also my AFS system which they gave me two new headlight and then the famous control arms that go out. trust me in the grand scheme of things you will be so happy that you have a warranty when things go bad. DO NOT OWN THIS CAR WITHOUT A WARRANTY!! Unless your loaded and could come out of pocket, this is my 4th LS and they all have minor issues that cost a lot to repair.
